Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, and in particular to a waste collection device after switching between multi-color materials in 3D printing. Background Technology

[0002] 3D printing technology builds three-dimensional objects by stacking materials layer by layer and is widely used in manufacturing, medical and other fields. Multi-color 3D printing requires frequent switching between different color materials. When switching, the original color material inside the nozzle needs to be discharged before switching to a different color material for printing. These original color materials are sprayed into the interior of the waste collection box through the nozzle, and different colors can be classified and stored for later remaking of the corresponding color material.

[0003] Existing 3D printers typically use multi-compartment collection devices for waste generated during color switching to facilitate the collection of waste of different colors. However, the number of compartments in existing waste collection boxes is fixed and cannot be adjusted; they are fixed in two, three, or other specifications. This requires purchasing multiple sizes to suit different printing needs, resulting in poor adaptability. When using multi-compartment waste collection boxes to collect less than the required number of compartments, the large number of compartments results in small individual compartment spaces, far less than the single-use capacity of a matching waste collection box, leading to poor flexibility and low practicality.

[0028] Please refer to Figures 1 to 6 Example 1:

[0029] This utility model proposes a waste collection device after switching multi-color materials in 3D printing, including: an outer cover assembly 1 and a dividing assembly; the outer cover assembly 1 includes a mounting base 101 and a collection drain plate 102, the mounting base 101 is fixedly installed on the waste collection workbench of the 3D printer, and the collection drain plate 102 is detachably fixedly installed on the top of the mounting base 101, and the top of the collection drain plate 102 is provided with a collection drain hole 1021; the dividing assembly is composed of a drive mechanism 2 and a dividing mechanism 3.

[0030] The drive mechanism 2 includes a drive motor 201, a zero-position shaft 202, and a rotating shaft 203. The drive motor 201 is fixedly installed at the bottom of the mounting base 101, and the zero-position shaft 202 is rotatably connected inside the mounting base 101. The rotating shaft of the drive motor 201 is connected to the bottom of the zero-position shaft 202 via a transmission connection, and the rotating shaft 203 is magnetically inserted into the top of the zero-position shaft 202. The dividing mechanism 3 includes a dividing plate 301 and a reference block 302. The reference block 302 is inserted into the side of the rotating shaft 203, and the dividing plate 301 is inserted into the outside of the reference block 302 and into the inside of the mounting base 101. The dividing mechanism 3 has six sets, and the number of dividing mechanisms 3 can be selected as needed.

[0031] The rotating shaft 203 has five sets of dividing positioning grooves on its side. These five sets of dividing positioning grooves are set at different heights on the rotating shaft 203. Each set consists of a different number of equal-dividing slots 2032. The number of equal-dividing slots 2032 in each set is six, five, four, three, and two, respectively. The equal-dividing slots 2032 in each set are arranged in a circular array on the rotating shaft 203. In use, the five sets of dividing positioning grooves are each provided with a different number of equal-dividing slots 2032. By inserting an appropriate number of dividing mechanisms 3 into the outside of the rotating shaft 203, the internal space of the outer cover assembly 1 can be divided into two, three, four, five, or six equal-dividing slots for use. This allows for the collection of waste of different colors and types, maximizing the volume of waste that can be temporarily stored at one time, and making it flexible and convenient to use.

[0032] The zero-position shaft 202 has a zero-position block 2021 on its side, and the bottom of the rotating shaft 203 has a zero-position groove 2031. The zero-position block 2021 is inserted into the zero-position groove 2031. In use, waste can be sprayed out through the nozzle, and the sprayed waste can fall into the interior of the outer cover assembly 1 through the collection hole 1021 for temporary storage and collection. Under the action of the dividing component, the interior of the outer cover assembly 1 is evenly divided into multiple compartments for use. The switching between compartments can be realized by the drive motor 201, thereby realizing the processing of different... The sorting and collection of colored waste materials, taking the use of a six-group dividing mechanism 3 as an example, divides the interior of the outer casing assembly 1 into six equally sized compartments. When the drive motor 201 rotates, it drives the zero-position shaft 202 to rotate. When the zero-position shaft 202 rotates, the zero-position block 2021 drives the rotating shaft 203 to rotate through the zero-position groove 2031. Thus, when the rotating shaft 203 rotates, it drives the six-group dividing mechanism 3 to rotate synchronously, achieving the switching of compartment positions. Due to the included angle between the six compartments... The angle is 60 degrees, so the drive motor 201 can drive the rotating shaft 203 to rotate 60 degrees within a single pulse electrical signal, realizing the switching between grids with accurate positioning. The rotation angle of the drive motor 201 within a single pulse electrical signal can be adjusted by the control device according to the actual number of grid mechanisms 3. When using five groups of grid mechanisms 3, there are five grids inside the outer cover assembly 1, and the angle between adjacent grids is 72 degrees. At this time, the rotation angle of the drive motor 201 within a single pulse electrical signal can be adjusted to 72 degrees. Similarly, the rotation angle of the drive motor 201 within a single pulse electrical signal can be adjusted as needed to adapt to the number of grid mechanisms 3 selected, ensuring accurate positioning when switching between grids. In each of the five groups of grid positioning slots, there is an evenly divided slot 2032 directly above the zero position slot 2031. This design makes it convenient to always position one grid at the reference zero position when switching the number of grid mechanisms 3 used, ensuring the accuracy of subsequent switching actions.

[0033] The working principle of this embodiment: The five groups of segmented positioning slots are each provided with a different number of equal-division slots 2032. By inserting an appropriate number of segmentation mechanisms 3 onto the outside of the rotating shaft 203, the internal space of the outer cover assembly 1 can be divided into two, three, four, five, or six equal-division slots for use. This can accommodate the collection of waste of different colors and types, maximizing the volume of waste temporarily stored at one time. The waste can be sprayed out through the nozzle, and the sprayed waste can fall into the interior of the outer cover assembly 1 through the collection hole 1021 for temporary collection. Under the action of the segmentation components... The interior of the outer casing assembly 1 is evenly divided into multiple compartments for use. Switching between compartments can be achieved via the drive motor 201, thus enabling the classified collection and use of waste materials of different colors. Taking the use of the six-compartment compartment mechanism 3 as an example, the six-compartment compartment mechanism 3 can divide the interior of the outer casing assembly 1 into six equal-sized compartments. When the drive motor 201 rotates, it drives the zero-position shaft 202 to rotate. When the zero-position shaft 202 rotates, the zero-position block 2021 can drive the rotating shaft 203 to rotate through the zero-position groove 2031. Therefore, when the rotating shaft 203 rotates, it can drive... The six-unit grid mechanism 3 rotates synchronously to switch the grid positions. Since the included angle between the six grids is 60 degrees, a single pulse electrical signal from the drive motor 201 can drive the rotating shaft 203 to rotate 60 degrees, achieving grid switching with accurate positioning. The rotation angle of the rotating shaft 203 driven by a single pulse electrical signal from the drive motor 201 can be adjusted according to the actual number of grid mechanisms 3 set by the control device. This is beneficial when using a five-unit grid mechanism 3, where the outer casing assembly 1 has five grids with an angle of 72 degrees between adjacent grids. The rotation angle of the rotating shaft 203 driven by a single pulse electrical signal of the motor 201 can be adjusted to 72 degrees. Similarly, the rotation angle of the rotating shaft 203 driven by a single pulse electrical signal of the drive motor 201 can be adjusted as needed to adapt to the number of selected grid-splitting mechanisms 3, ensuring accurate positioning between grids. In addition, one equal-division slot 2032 in each of the five grid-splitting positioning slots is located directly above the zero-position slot 2031. This design makes it convenient to always position one grid at the reference zero position when changing the number of grid-splitting mechanisms 3 used, ensuring the accuracy of subsequent switching actions.
